Check out the cooler master n200. I had to buy a micro atx case a few months ago so I did tons of research. Multiple drive mounting options. You can take the drive cage out and still have the ability to install ssds and hdd in the 3.5 bay under the optical bay. When you take the drive cage out, this allows you unrestricted dual 120mm air flow fans for intake. You also have side, top and rear fan mounting options. Just make sure you route the cpu power supply cable behind the motherboard before you mount it.
